To all 'whom it may concern:

Be it known that I, JOHN .ARMs'rnoNo,

' be produced of very furnace. however,

- down into a well below the ov'en, and be drawn out therefrom, or pulled out at the side of the oven l,and carried ctil on an inclined 'or lhorizontal railway or conveyer. The coke was thus considerably broken, and owing to surface oxidationV had an uneven and poor. color. L

Now my present invention is designed to do agay with thesecvils and is set forth in the accompanying drawings, in which l placed outside,

meet, `or in place of having two sets meeting, a, single set can he driven right across'the chamber. Theprongs are preferably considerably deeper than they are broad so as to form girders as it-were.

C is a ram working vertically inside the cylinder E. This cylinder E can he moved forward or backward on the rails H by means of wheels Gr.

B is a movable brought up against forms animpervious platform on the top of thisA movable bottom, of it. Y

A Aare supports or ledges on the side of' the cylinder to support the bottom in its lowest position when 'the ram is .lowered out of the cylinder. l The modeof action in using this apparatus for vertical or even for somewhat in clined ovens or retorts is as follows z-When the oven or retort is full of coke, and a or the whole bottom, which when the ram supporting but otherwise free forks F F are pushed through their respecthe retort chamber, bottom. D is a little tive holes into kthe bottom of the oven. They vpenetrate the coke until there is a grate formed all over the bottom. When this. 1s done, and the coke is firmly secured, the bottom B is taken away, and the caisson or cylin-l deris run immediately under the oven or retort, and iixed'in position by bolts or other- The ram is then raised from the lower shown at D', lifting up the loose position on the ledges or immediately un;`

are withdrawn, and

done, the forks F F the charge is now on which is lowered to the position shown at4 B, but before it is lowered quite so far, if the column of cokein theV oven or retort capable of resting on the'bottom is taller than the cylinder, the forks are again ap-` plied both to arrest the coke descending, and to cut it olf at this point. The ram now descends farther till the bottom B rests on the' ledges Ak A. The ram is then lowered toftle'position shown at D when the cylinder with its contents 'of hotcoke is removed the head of the ram,

ven tlie wheels-G G on the' rails, to be quenched in the cylinder outof contact with.f air. ln making hard coke it is not-necessary that the` forks should go right th'rough the coke; they penetrate an inch or two itis sulliciei'it. I ln the construction shown in Figs. 5, 6,- and 7, B is the bottomlof the cylinder. P

is a pusher, formed with wedge-shaped por-y tions upon its upper'surface, as shown at lV. "This pusher is'- normally placed asl shown, but may be pulled out as required.

- The mode'of operation oivthis s'trutltu're is as follows: The tops of the 'carriages are recsuccesl tangular, as shown, and they p v v sively under the furnace.Y lVlien it is desired to fill theione immediately under tl'ieifui` nace, the prongsll", Fig. 3, are withdrawn,

'about two inches.

and the coke falls down into the carriage, ,A

filling the same.` rlfhe prongs F are now rammed back into their position, the pusher ispiilledout, allowing the bottom to drop This enablesthe coke un der thevprongs to sink to thelevel of the carriage. The empty carriage behind`this `carriage is now pressed forward, pushing for the` other.

the iirst carriage out from under the fui'- nace,V and taking its place; a lid or cover of any kind lis placed on the first carriage, and it is carried away to be cooled and emptied, and the cycle is-repeated lwith' the second4 carriage. i

' In the operation of the inodified-eonstruc- .tion just described, the successive carriages maintain the furnace practically sealed against the admission of air at the bottom, even during the substitution ot one carriage resistance to the descent and also 'an air.-

cushioning actionyduerto the retarded escape of air around the sides oi tlie'descending coke lump, which greatly reduce the shock. The .chai'ge,vtliougli soniewliat cracked or broken, retains its original shape and din'iensions, and litting tightly the carriage is protected against excessive oxidation. Consequently, while the ii'iodilied construction isnot the full etpiivaleiit of the pi'ctei'red construction. it nevertheless attains in a more or less limited degree the charactei'istic advantages ol' in v invention.

i l declare that' what'l claim isty l.. The combin-,ition with a coke oven open at the lower end. and having sides substantiallyY parallel and vertical; means for teinpoi'ai'ily holding the contents of the oven in rl`liel omission of' the rain is4 j position; and a receptacle for receiving the closely to said. lower end, the receptacle and the oven heilig of substantially thev saine cross-section, whereby `when the means'ifor holding the coke are withdrawn or removed, the coke falls into'the, receptacle without being exposed to the air, and without fracture, all arching, such as is occasioned when the lower `end of the oven is contracted, being prevented.

2. In combination with -a coke oven, a series of receptacles for removing the coke dis,

charged from the lower end of the oven, said receptacles being internally of similar horizontal cross-section to that of the lower end' of the oven, and making a relatively close lit with said lower end; a movable bottoni in ries of carriage-like receptacles adapted to be moved beneath the saine and into which the coke is discharged, said receptacles each 4having an internal cross-section substantially .conforming in shape to the lower discharge end of the oven; a movable bottom carried in each receptacle; and means for raising and llowering said bottoms.
